I solved that now. But now I got a new problem.
Just so you know; I don't got any experience with ManiaLive. I've set up many servers with Xaseco previously, but I'm new to ManiaLive.
Now it gives me a new error; see the screenshot.

Oh; I see a mistake in the picture, I said database name was yuffy, but changed it to yuggy. But the error keeps existing.
